Heat Pump Repair in Charleston, SC

Because heat pumps run both directions, failures show up differently. Our techs train specifically on these systems, not just general repair.

General HVAC techs are often less confident with heat pumps since the reversing valve, defrost board, and aux heat strips don't exist on a standard split system. We test each component specifically, since a heat pump issue in January often has nothing in common with the same symptom in July.

FAQ

Frequently Asked Questions

What Charleston heat pump owners ask most.

Nine times out of ten this points to a reversing valve stuck in the wrong position, though we still check refrigerant charge since it can mimic the same symptom.

The signal isn't reaching the strips the way it should.

These two components simply don't exist on a conventional system.

Year-round, both heating and cooling mode failures covered.

Not just the mode it's currently running in.

Yes, defrost logic and staging vary meaningfully between manufacturers.

Not inherently, though the auxiliary heat strips see more use in harsher climates and are worth checking during maintenance.
